SUMMARY
Differences in inherited resistance among seven sugar-beet stocks had similar effects on Myzus persicae clones representing the range of variation in aphid response to resistant and susceptible sugar beet observed in fifty-eight clones collected between 1969 and 1971. Three sugar-beet stocks were consistently resistant. Statistically significant interactions between beet stocks and aphid clones did not indicate the existence of biotypes with specific abilities to overcome resistance. M. persicae clones differed in their vigour of colonizing sugar beet, irrespective of the differences between beet stocks. The readiness of adult aphids to settle determined the size of aphid population produced and included a component related to the response of the aphid clone to sugar beet as a host, and a component related to the resistance ranking of the beet stock. Breeding sugar beet with resistance to aphids will be simplified, as the results indicate that, at present, differences between aphid biotypes need not be considered a problem.read more

The genetic structure of host plant adaptation in a spatial patchwork: demographic variability among reciprocally transplanted pea aphid clones.
TL;DR: The structure of genetic variation for host use reveals patterns of local adaptation, probable selective consequences of migration between hosts, and the potential for further evolution.

Genetic variability in host plant adaptation of the green peach aphid, Myzus persicae
TL;DR: A wide genetic variability in host plant adaptation to sugar beets as well as to potatoes is revealed and both traits seem to be inherited independently from each other and do not correlate with clone‐specific host plant preference of apterous adults.

Aphid genotypes, plant phenotypes, and genetic diversity: a demographic analysis of experimental data.
TL;DR: This paper hypothesizes that there is an interaction between aphid genotypes and host plant phenotypes such that no aphid clone is relatively most fit on all host phenotypes, and reports on an experiment designed to test this hypothesis.

Settling behaviour and reproductive potential of the green peach aphid Myzus persicae on peach varieties and a related wild Prunus
TL;DR: The results showed that distinct mechanisms were involved in the sources of resistance studied and the ranking of the genotypes on their resistance/susceptibility status remained roughly stable throughout the experiments, providing evidence that aphids on this genotype lacked sufficient ressources to be directed both towards production and growth of embryos.

Variation in the photoperiodic response within natural populations of Myzus persicae (Sulz.).
TL;DR: The responses to short photoperiod of clones of Myzus persicae (Sulz.) established from random samples of summer populations in southern England were generally stable and characteristic for each clone, and holocyclic and androcyclic forms are most common.

TL;DR: When aphids are overcrowded or feed on host-plants of poor quality, many aphids reach maturity that might otherwise fail to mature because of the ability of the species to produce viable adults of a great variety of size, including very small adults.

TL;DR: Control by C. carnea of aphid populations developing on glasshouse chrysanthemum plants can be predicted mathematically, and at very low aphid densities control was less effective.

TL;DR: The results showed that biotypes of the aphid, with differing abilities to colonize respective sprout clones, existed in each area, and of the sevenSprout clones resistant to the Wellesbourne aphids, only one appeared never to be fully susceptible to one or more of the other biotype of B. brassicae.
